AirPlus is one of the payment sources you set up yourself as a corporate payment method in the Corporate portal. An overview of all options is given in Corporate payment methods.
Create the configuration
In the Corporate portal, under Issuing & Payments, you open the wizard via Add Configuration and choose AirPlus as the payment source.
For an AirPlus configuration you enter a name, the Business Unit, the Account Number and the Financial Account Type (Procurement or BTM Financial Account).
Map the accounting fields
You then define for each accounting field (e.g. cost center, employee number, project number, department code or internal account) whether it is Not Used, Optional or Mandatory, and map it to the matching data field of your Company. This way the right values automatically end up on your statement. Fields such as order number, departure date and destination are taken over automatically from the transaction.
